Dispersive, specific and total surface energies for carbon fibres and polymers. The surface energy of the individual components can now be used to estimate the interaction between each polymer-fibre pair. Such an estimation is obtained from the calculation of the work of adhesion, WA by applying Eq.1. WA total = 2(1 d d* 2) 1/2 + 2(1 sp *
